MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -In computer science, graph traversal (also known as graph search) refers to the process of visiting (checking and/or updating) each vertex in a graph. Such traversals are classified by the order in which the vertices are visited. Tree traversal is a special case of graph traversal.

Detailed explanation-2: -Dijkstra’s Algorithm finds the shortest path between a given node (which is called the “source node") and all other nodes in a graph. This algorithm uses the weights of the edges to find the path that minimizes the total distance (weight) between the source node and all other nodes.

Detailed explanation-3: -To traverse a graph is to process every node in the graph exactly once. Because there are many paths leading from one node to another, the hardest part about traversing a graph is making sure that you do not process some node twice.

Detailed explanation-4: -Dijkstra’s algorithm (/ˈdaɪkstrəz/ DYKE-strəz) is an algorithm for finding the shortest paths between nodes in a weighted graph, which may represent, for example, road networks. It was conceived by computer scientist Edsger W. Dijkstra in 1956 and published three years later.
